Specification of Letters Patent.

Patented Apr. it, 191?.

Application filed October 18, 1916. Serial No. 126,301.

To all whom it may concern Be it known that I, ANDREW C. ZwARIoH, a subject of the Czar of Russia, residing at Homestead, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Motors, of which the following is a specification.

This invention relates to motors for driving machines or for other purposes wherein it is found applicable and has for its object to provide a device of such type, with means, in a manner as hereinafter set forth, for changing an intermittent rotary motion into a continuous one.

Further objects of the invention are to provide a motor which is simple in its construction and arrangement, strong, durable, efficient in its use, readily set up, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an elevation of a motor in accordance with this invention.

Fig. 2 is a section on line 11-11, Fig. 1.

Fig. 8 is a detail of the resilient elements.

Fig. 4 is a detail illustrating the driving element.

Referring to the drawings in detail 1 denotes a stationary shaft, provided with a crank 2 intermediate its ends and the shaft 1 is mounted upon a pair of uprights 3.

Rotatably mounted on the shaft 1, between the uprights 3, is a pair of opposed carriers 4, 5, in the form of elongated rectangular plates. The carriers 4, 5, are positioned at each side of the crank 2 and are secured to opposite sides of a circular band 6 having peripheral teeth 7. The ends of the carriers 4, 5, terminate inwardly with respect to the teeth 7 and said ends are welded to the member 6.

Loosely mounted on the crank 2 is a disk 8 which is eccentrically disposed with respect to the member 6. Loosely connected to the di k 8, as at .9, are the inner ends of a series of shifting elements 10, 11, 12 and 13, and the outer ends of the said shifting elements are anchored, as at 14, to the inner ends of the member 6. The outer ends of the shifting elements are arranged equidistant with respect to each other and each of sa1d elements consists of a contractible and expansible coil spring. Fixed to the outer face of the carrier 4 is a ratchet wheel 23 and fixed to the outer face of the carrier 5 is a ratchet wheel 24, the latter being reversely disposed with respect to the former. Associated with the ratchet wheels 23, 24, are actuating members ea ch consisting of a lever and a pivoted pawl 26. The lever 25 is connected with an operating device 27 driven from a prime mover. Each ratchet wheel and its actuating member is termed a driving element and each is adapted to intermittently revolve the carrier which will in turn carry the member 6 therewith. One driving element shifts the carrier in one direction and the other the other carrier in the opposite direction.

The uprights 3 carried by a base 28, have supports 29 for a shaft 30, the latter is pro vided with a gear wheel 31 which meshes with the teeth 7. The shaft 30 carries a pulley or gear wheel 32 for transmitting motion to the point desired.

The carriers 4, 5, member 6 and elements 10, 11, 12 and 13 constitute what may be termed a rotor.

The elements 10, 11, 12 and 13 are employed to set up a continuous rotatory motion for the intermittent drive, that is to say the rotor is intermittently operated by a driving element the shifting elements expand and contract and during the contracting movement thereof causes the rotor to revolve and this movement is had in view of the fact that the disk 8 is eccentrically disposed with respect to the member 6 and carriers 4, 5, and further the inner ends of the shifting members being off center. When the shifting element 12 assumes the position illustrated in Fig. 3 it is completely contracted and as the rotor revolves it will gradually expand until it assumes the expanded position as illustrated in connection with the element 11 in Fig. 2. On further movement of the rotor the shifting element will expand in a manner as illustrated in connection with the member 10 in Fig. 3. As the rotor continues to rotate the shifting element will contract as illustrated in con nection with the element 13, in Fig. 3, and by the foregoing manner of contracting and expanding the shifting elements the intermittent impulse given to the rotor by the driving element will be changed into a continuous motion.

What I claim is 1. A motor comprising a stationary crank shaft, a disk carried by the crank of the shaft, a pair of opposed elongated rectangular plates revolving upon said shaft at each side of the crank thereof, a peripherally toothed circular band interposed between and having its edges connected to the inner. faces of said plates, means for intermittently rotating one of said plates carrying said toothed band therewith, and a series of expansible and contractible pulling members arranged within said band and having'their inner ends connected with said disk at equidistant points and their outer ends connected with the inner face of said band at equis distant points and providing means for changing the intermittent drive of the carrier into a continuous one.

2. A motor comprising a stationary crank Copies of this patent may be obtained for shaft, a disk carried by the crank of the shaft, a pair of opposed elongated rectangular plates revolving upon said shaft at each 7 side of* the crank thereof, a peripherally r toothed band therewith, and a series of eX- 1':

pansible and contractible pulling members arranged within said band and having their inner ends connected with said disk at equidistant points and their outer ends connected with the inner face of said band at equidistant points and providing means for changing the intermittent drive of the carrier into a continuous one, and a transmission mechanism including a gear meshing with the teeth of said member.

Intestimony whereof I my signature in the presence of two witnesses.
